Explore major industrial gases used by Sri Lankan factories,
workshops, engineering companies, food processors, laboratories,
construction teams and other commercial users. Gass.lk provides
clear product information and quotation pathways for gas supply,
cylinders, refills, high-purity gases and application-specific
requirements.
Find the Right Industrial Gas for Your Requirement
The correct gas depends on the application, required purity,
cylinder size, gas consumption, operating environment and safety
requirements. The sections below explain the most common
industrial gas categories and where they are typically used.

systems, cylinders, regulators, flowmeters and healthcare gas
safety information.
Industrial oxygen supports combustion and is widely used in
oxy-fuel cutting, welding, brazing, metal processing, glass and
ceramic production, wastewater treatment and selected
manufacturing processes. Oxygen may be supplied in compressed
cylinders or, for higher-volume requirements, through bulk or
liquid systems depending on availability.

Argon is an inert shielding gas commonly used in TIG welding and
selected MIG welding applications. It is also used where an
oxygen-free or inert atmosphere is required, including some
laboratory, metallurgical and manufacturing processes.
Nitrogen is an inert gas used for purging, blanketing, pressure
testing, food packaging, laboratory work and
controlled-atmosphere processes. Liquid nitrogen is also used in
cooling, freezing and specialist industrial or laboratory
applications.
Carbon dioxide is used in beverage systems, food processing,
welding, refrigeration-related applications and multiple
industrial processes. The required grade should be confirmed
carefully, especially for food or beverage use.
Acetylene is a high-temperature fuel gas used with oxygen for
cutting, welding, brazing and heating. It is normally supplied
in specially designed dissolved-acetylene cylinders and requires
careful handling and correct regulator selection.
Helium is a light, inert gas used in specialized industrial,
laboratory and technical applications. Depending on the
requirement, users may need specific purity levels, cylinder
sizes or controlled supply arrangements.
Laboratories, electronics, calibration, research and advanced
manufacturing may require gases with defined purity or
composition. These can include high-purity nitrogen, high-purity
argon, specialty gases and controlled gas mixtures.
Some welding, laboratory, calibration and industrial
applications require a mixture of gases rather than a single
gas. The exact composition should be selected according to the
process specification and equipment requirements.
Welding gas selection affects arc stability, penetration, bead
appearance, oxidation and overall weld quality. Common
welding-related gases include argon, CO₂, oxygen, acetylene and
selected shielding gas mixtures.
Industrial Gas Cylinders, Refills and Exchange Enquiries
Industrial gases are commonly supplied in cylinders, but the
correct cylinder type and fill arrangement depend on the gas,
pressure, ownership model, supplier policy and application.
Customers should confirm whether they require a new cylinder,
refill, exchange, rental or another supply arrangement.
For a faster quotation, provide the cylinder size or water
capacity if known, current cylinder ownership information,
required gas and quantity, and your delivery location.
What to Consider Before Choosing an Industrial Gas
Application
The same gas can be used for different processes, but equipment
settings and required grade may differ. Always start with the
actual application, such as TIG welding, purging or food
packaging.
Purity & Grade
Industrial, food-grade, laboratory and high-purity gases are not
interchangeable in every application. Confirm the required
specification before ordering.
Consumption & Supply Mode
Small users may prefer cylinders, while larger users may need
manifolds, packs or bulk supply. Consumption volume helps
determine the most practical option.
Pressure & Equipment
Regulators, hoses, valves and downstream equipment must be
suitable for the gas and operating pressure. Do not assume one
regulator can be used across all gas types.
Delivery & Storage
Cylinder storage, ventilation, handling and transport conditions
matter. Delivery feasibility also depends on location, quantity
and supplier service coverage.
Safety & Compliance
Industrial gases can be compressed, oxidizing, inert, flammable
or cryogenic. Users should follow supplier instructions, labels,
safety data sheets and applicable workplace procedures.
Frequently Asked Questions
Industrial Gas Product Questions
Which industrial gases are commonly used in welding?
Common welding-related gases include argon, carbon dioxide,
oxygen, acetylene and selected gas mixtures. The correct choice
depends on the welding process and material.
Can industrial gas cylinders be refilled?
Refill or exchange availability depends on the gas, cylinder
ownership, cylinder condition, supplier policy and applicable
safety requirements. Confirm the cylinder details when
requesting a quote.
Do I need to specify gas purity?
Yes, when the application requires a particular grade.
Laboratories, food applications and certain manufacturing
processes may need a defined purity or specification.
How do I request current pricing?
Send the gas name, quantity, cylinder size or supply format,
application and delivery location. Current commercial pricing is
best provided through a quotation.
